Mifare DESFire card

Mifare desfire card is also called Smart card, Intelligent card, Microcircuit card or microchip card.It is a microelectronic chip embedded in a card base that conforms to ISO 7816 standard and is made into a card form.The communication between the Mifare desfire card and the reader can be contactless or non-contactless.The Mifare desfire card is categorized by communication interface into contactless Mifare desfire card, contactless IC card and dual interface card (both contactless and contactless communication interfaces). The Mifare desfire card not only stores basic user information, but also carries and transmits images of the vehicle.The Mifare desfire 4K byte induction Mifare desfire card is adopted, so that the vehicle image information does not need network transmission, and is carried directly by the Mifare desfire card to reduce the network pressure, and the vehicle image and vehicle information are transmitted through the Mifare desfire card to solve the problem of cheating in the exchange of road toll CARDS
